BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-held position input device which is connected to an information processing device and operated by moving on a surface, and in particular, to simplify the process of forming parts and to facilitate assembly of the device. A position input device.

2. Description of the Related Art In recent years, in information processing apparatuses having a display, a hand-held position input device (hereinafter, referred to as a mouse) that is operated while moving on a surface with one hand has been widely used as a means for moving a cursor on the display. I have. However, the conventional mouse is relatively expensive, and there is a demand for a mouse with a reduced price.

[0003]

2. Description of the Related Art FIG. 3 is a diagram showing a main part of a conventional mouse. In the plan view shown in FIG. 3 (a) and the sectional side view shown in FIG. 3 (b), the conventional mouse has a container. The container is composed of a base 1 and a cover 2 made of molded plastic, and a plurality of switch elements 4 mounted on a printed circuit board 3 are fixed to a switch mounting base 11 of the base 1. A ball 5 is inserted into the base 1 and is rotatably held by a lid 12 fitted into the base 1.

Further, two encoders 6 in which, for example, a roller 61 abuts on the ball 5 are incorporated in the base 1,
When the ball 5 rolls, the roller 61 and the disk 63, which are rotatably fixed via a rotation shaft 62, rotate, and a signal in the X-axis direction and a signal in the Y-axis direction are output from the sensor 64, respectively. Have been. Shoe 13 and 14 joined to the lower surface
Is made of Teflon or the like to facilitate mouse movement.

On the other hand, the cover 2 is provided with a plurality of push buttons 7 which pass through holes (not shown) of the cover 2 and are exposed on the surface, and a plurality of push buttons 7 integrated with the mounting base 72 via a spring member 71. Reference numeral 7 is fixed to the cover 2 by heat swaging or the like. When the cover 2 is mounted on the base 1, the lower surface of the push button 7 comes into contact with the switch element 4.

[0006]

However, in the conventional mouse, the base, the cover, and the push button are separately formed, and then the cover and the push button are integrated, so that the number of parts increases and the cost required for processing the parts increases. There was a problem that assembly cost was required.

It is an object of the present invention to provide a mouse which reduces the number of parts and reduces the cost of processing and assembling parts.

[0008]

FIG. 1 is a diagram showing a main part of a mouse according to the present invention. The same object is denoted by the same symbol throughout the drawings.

The above-mentioned problems are caused by the base 8 and the cover 9 made of molded plastic and the printed circuit board 3.
A plurality of switching elements which are fixed to the base 8 is mounted on 4
When, a plurality of push button 7 which is exposed to the surface through the contact and the cover 9 to the switching element 4, through the spring member 83
The push button 7 supported by the base 8 is achieved by the position input device of the present invention integrally formed with the base 8.

[0010]

[Function] In FIG. 1, a plastic base and
And cover, supported by base via spring member
In the position input device of the present invention , in which the push button to be formed is integrally molded with the base , the push button and the spring member are mounted on the cover after molding.
Compared with the conventional position input device to be worn, the number of parts is reduced, the cost required for parts processing is reduced, and the push button is covered after molding
This eliminates the need for the work of mounting the device on a vehicle, thereby reducing the cost required for assembly. In other words, it is possible to realize a mouse in which the number of parts is reduced and the cost for processing parts and the cost for assembling are reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 2 is a diagram showing the base of the mouse according to the present invention.

In the plan view shown in FIG. 1 (a) and the sectional side view shown in FIG. 1 (b), the mouse according to the present invention comprises a base 8 and a cover 9 made of molded plastic in a container. A plurality of switch elements 4 mounted on the printed circuit board 3 are fixed to the switch mounting base 81 of the base 8. The ball 5 is inserted into the base 8 and held rotatably by a lid 82 fitted into the base 8.

Further, two encoders 6 in which a roller 61 abuts on the ball 5 are incorporated in the base 8, for example.
When the ball 5 rolls, the roller 61 and the disk 63, which are rotatably fixed via a rotation shaft 62, rotate, and a signal in the X-axis direction and a signal in the Y-axis direction are output from the sensor 64, respectively. Have been. Shoe 13 and 14 joined to the lower surface
Is made of Teflon or the like to facilitate mouse movement.

The push button 7 that passes through a hole (not shown) of the cover 9 and is exposed on the surface of the cover 9 is different from a conventional mouse.
As shown in FIG. 1B, each is supported by a base 8 via a spring member 83, and the push button 7, the spring member 83, and the base 8 are integrally formed of the same plastic.
The spring member 83 made of metal for supporting the push button 7 may be insert-molded during molding.

FIGS. 2A and 2B show the base of the mouse according to the present invention. FIG. 2A shows the upper surface, and FIG. 2B shows the lower surface.
The base 8 has a switch mount 81 and a switch mount 81 on the upper surface.
A ball storage chamber 84 having a push button 7 formed therebetween and having an opening on the lower surface and housing the ball 5 and the roller 61 therein protrudes upward. Further, a shallow circular recess 85 formed around the ball accommodating chamber 84 for fitting the lid 82 on the lower surface, and the shoe 13
And a concave portion 87 for bonding the shoe 14 are formed.

In a mold for integrally molding the push button 7 and a spring member (not shown) together with the base 8, the core for forming the lower surface of the push button 7 must pass through the base 8 and extend above the switch mounting base 81. No. Therefore, a plurality of square holes 88 through which the core penetrates are provided in the concave portion 86 that is hidden by joining the shoes 13.

Thus, the base made of plastic
And a cover, supported by a base via a spring member.
In the position input device of the present invention , in which the push button to be accepted is integrally molded with the base , the push button and the spring member are attached to the cover after molding.
Compared to the conventional position input device to be mounted, the number of parts is reduced, the cost required for parts processing is reduced, and the push button after molding is covered.
This eliminates the need for the work of mounting on the vehicle and reduces the cost required for assembly. In other words, it is possible to realize a mouse in which the number of parts is reduced and the cost for processing parts and the cost for assembling are reduced.

[0018]

As described above, according to the present invention, it is possible to provide a mouse in which the number of parts is reduced and the cost for processing parts and the cost for assembling are reduced.
